Pixar Animation Studios has laid off an undisclosed number of people at its Emeryville, Calif., headquarters due to the delay of its forthcoming film The Good Dinosaur, according to a report by The Los Angeles Times.

The layoffs reportedly affect less than five percent of the company's 1,200-person workforce, In September The Good Dinosaur was pushed back from its original release date of May 30, 2014, to Nov. 25, 2015. About a month before the project was delayed, the studio, a unit of Walt Disney Studios, removed director Bob Peterson from the project.

"At Pixar, we are constantly re-evaluating the creative and business needs of our studio," a Pixar representative said. "With the release date change of 'The Good Dinosaur,' we have realigned our production and support priorities, which includes a small reduction in our staffing levels."

The Good Dinosaur is based on the premise that an asteroid never hit Earth, causing the creatures and humans to live together. The project is being retooled, but Pixar has not yet named a replacement for Peterson.
